In order to evaluate neurologic development, postural reflexes were tested in normal kittens from birth through 7 weeks of age until stable adult patterns of performance were attained. These reflex tests included: body and air righting, visual placing, chin placing, tactile placing, hopping, and locomotion. A protocol for scoring responses was designed for each individual reflex to differentiate their progression. The first reflexes to mature were visual placing, chin placing, and body righting which attained a maximal score during the 3rd week of life. This was followed by maturation of the forelimb hopping reflex and independent locomotion during the 4th week. Forelimb tactile placing responses, hind limb hopping reflexes, and air righting developed by the 5th week. Hind limb tactile placing responses were the last to mature. They became fully expressed in the 6th week. The pattern of ontogeny of these reflexes proceeded in a cephalocaudal direction. This is in agreement with earlier observations of others who correlated the maturation of reflex responses in kittens with myelination in the central nervous system.
为了评估神经发育情况，对正常小猫从出生到7周龄进行姿势反射测试，直至达到稳定的成年表现模式。这些反射测试包括：身体和空中翻正、视觉放置、下巴放置、触觉放置、跳跃和运动。针对每个单独的反射设计了一个评分反应方案，以区分它们的进展。最早成熟的反射是视觉放置、下巴放置和身体翻正，在出生后第3周达到最高分。随后是前肢跳跃反射和独立运动在第4周成熟。前肢触觉放置反应、后肢跳跃反射和空中翻正在第5周发育。后肢触觉放置反应是最后成熟的。它们在第6周完全表现出来。这些反射的个体发生模式是从头尾方向进行的。这与其他人早期的观察结果一致，他们将小猫反射反应的成熟与中枢神经系统的髓鞘形成联系起来。
